"The ability to change pages by using your thumb on the wheel meant that you could quickly move through a story without breaking your stride"

Participant in EBONI hardware evaluation

Careful design of buttons or dials for turning pages can improve this aspect of the paper book metaphor, leading to a smoother, faster transition from one page to the next. In EBONI's evaluations, users of the devices which employ dials commented that they felt they could read faster using this method of page turning. This is particularly important for texts which are read sequentially, such as novels. Simple "page forward/page back" buttons are felt to be intuitive, but buttons should be large, as opposed to small and fiddly.


21.1 Dials or simple buttons should be used for page turning
21.2 Buttons should be large
